  • CPAP continuous positive airway pressure
  • variable airway pressure wherein the pressure provided to the airway of the patient is varied with the patient's respiratory cycle.
  • Such therapies are typically provided to the patient at night while the patient is sleeping.
  • Non-invasive ventilation and pressure support therapies as just described involve the placement of a patient interface device including a mask component having a soft, flexible sealing cushion on the face of a patient.
  • the mask component may be, without limitation, a nasal mask that covers the patient' s nose or a nasal/oral mask that covers the patient's nose and mouth, among other configurations.

  • the sealing cushion typically has a support portion coupled to a sealing portion, which may integrated together as a single part or that may be separate components that when combined together in the final assembly provide the sealing and support functions.
  • the patient interface device is connected to a gas delivery tube or conduit and interfaces the ventilator or pressure support device with the airway of the patient, so that a flow of breathing gas can be delivered from the pressure/flow generating device to the airway of the patient. It is known to maintain such devices on the face of a wearer by a headgear having one or more straps adapted to fit over/around the patient's head.
  • a nasal/oral mask may employ a nasal/oral mask or a nasal mask. It would be advantageous, however, to have a patent interface device that employs a mask component that may be converted from a nasal/oral mask to a nasal mask and back as desired to suit the needs of the patient.
